Okay (just to make it clear, I’m using the SEPv1/SEPv2 in the comparison, but I’ll just say M1A2 since I’m lazy)
M1A2 vs Type 10
Similar mobility. Type 10 wins in firepower, profile and hull down capability, Abrams wins in turret armor and versatility (less overall depression, but better gun handling and no need to use the clunky suspension). Neither are especially survivable.
M1A2 is still the better tank, but it’s not a massive gap.
M1A2 vs Leclerc
M1A2 vs Leclerc: Similar mobility and firepower is a sidegrade (M1A2 has more pen, but 5 seconds autoloader beats 5 second manual loader any day). Leclerc is smaller profile but weaker turret armor while the Abrams is larger but has better turret armor. Again, neither has much survivability to write home about.
Same as above, the M1A2 still comes out on top but it’s not a big gap.
M1A2 vs Merkava Mk.4
M1A2 has slightly better forward mobility, Merkava has considerably better reverse mobility. Firepower is pretty much equal. M1A2 has more consistent turret armor while the Merkava has better overall survivability.
These tanks are really really close (just a shame that the Spyder is so bad it makes playing Israel 12.7 a pain)
M1A2 vs CR2
(still unlocking the BN and 2E, so most of my experience is with the CR2/CR2 OES/CR3 TD)
M1A2 beats the BN in terms of mobility and firepower. The CR2s get a slight boost in survivability due to the spall liners and no turret basket. BN has the APS which is incredible at longer ranges.
CR2E is closer to the M1A2 in mobility, but loses the APS.
First comparison where the M1A2 is better with a considerable gap
These are the most comparable tanks to the M1A2s. I’m not even going to waste my time comparing the M1A2 to the Ariete AMV, T-90M and T-72B3A, as these 3 are obviously much worse than the M1A2.
